Rotor RPM decayed at 100 ft on final approach, approximately 150 m from the landing point. The pilot was unable to recover from the situation, and autorotated on to a slope. The helicopter slid down 5-6 m, breaking the tail boom and one skid. No defect s were found. The pilot had very limited experience on the helicopter type and did not recognise the onset of low rotor RPM. This required proactive control inputs, including rolling on throttle. Due to the height above ground and the descent rate, impact with the ground could not be avoided. Pilots are reminded to actively monitor the rotor RPM and to manage the required control inputs.
